Definitions
- the present invention relates to novel stilbazolium salt, and preparation and use thereof. More specifically, the present invention relates to novel stilbazolium salt prepared by using terephthalaldehydemonodialkylacetal, processes for preparation thereof, and use of thus prepeured stilbazolium salt for preparation of a photosensitive resin.
- Stilbazolium salt forms a photosensitive resin of high sensitivity (“PVA-SbQ type resin") when it is combined with polyvinyl alcohol (“PVA”).
- PVA polyvinyl alcohol
- the PVA-ADC (ammonium dichromate) type photosensitive resin or PVA-Diazo type photosensitive resin has been commonly used as a photosensitive resin for fluorescent slurry of color Braun tube.
- the PVA-ADC type or PVA-Diazo type resin has been recently substituted with the PVA-SbQ type resin because it exhibits from several to several dozens of more folds of activities as compared to the conventional PVA-ACD type or PVA-diazo type photosensitive resin, and thus the former two types are presently considered as highly valuable for the purposes of fixation of enzyme, screen printing, preparation of color picture tube, color filter or the like.
- a photosensitive liquid using the PVA-SbQ type resin has a great advantage in that it causes very little environmental pollution unlike the conventional photosensitive resin.
- the conventional PVA-ADC type photosensitive resin contains chromium, a type of heavy metal, and PVA-diazo type photosensitive resin contains a large amount of toxic diazo compound in order to increase sensitivity, so that both resins axe serious environmental hazards.
- the PVA- SbQ type resin is presently being used as a substitute for the PVA-ADC or PVA-diazo type resin.
- the problem with the PVA-SbQ type resin is that the process of preparing SbQ salt, used as a raw material of the resin, is complicated and inefficient. Therefore, development of a process for efficient preparation of SbQ salt is required in the art.
- TA terephthalaldehyde
- the first process comprises reacting a compound of picoline type or methylquinoline type with terephthalaldehyde; purifying the product thus obtained; and reacting the product with an alkylating agent to synthesize SbQ salt.
- the process has problems in that 1) an excess amount of TA is used in order to avoid dimeric byproduct, 2) the material used in the purifying process is very toxic, and 3) a complicated process comprising 7 steps (i.e., (a) removing the unreacted TA by using aqueous hydrochloric acid, (b) removing the unreacted TA by using benzene, (c) neutralizing with aqueous sodium hydroxide, (d) drying SbQ and dimeric byproducts, (e) removing the dimeric-byproducts by using ethyl acetate, (f) removing the ethyl acetate and drying SbQ, and (g) synthesizing SbQ salt by using dimethyl sulfate) are required.
- the second process comprises reacting a compound of picoline type or methylquinoline type with an alkylating agent, and adding TA to the reaction mixture to prepare SbQ salt.
- multi-step purifying process has been somewhat simplified, but the problem of using an excessive amount of TA still remains.
- the process for purifying SbQ salt according to the second process comprises the steps of (a) removing the dimeric byproduct from the reaction mixture, (b) treating the reaction mixture with a mixed solvent of ethanol and acetone, and (c) filtering and drying SbQ salt.
- the complicated purifying processes have been simplified somewhat in this three-step process, a method of removing the dimeric byproducts has not been described.
- a novel photosensitive group can be manufactured in a large amount by using a material of which one of the two aldehyde groups had been protected by acetal group, i.e., terephthalaldehydemonodialkyl acetal
- TDA TDA
- the present invention provides a stilbazolium salt ("SbQ-A salt”) as a photoreactive compound which is represented by the following formula (1) or (1A) :
- R 1 and R 2 being identical to or different from each other, independently represents hydrogen atom, alkyl group, aryl group, allyl group, aralkyl group or allylalkyl group, wherein hydroxyl group, amide group, carboxylic group, ether bond, double bond, or the like may be included in each group; and
- X- represents halogen ion, sulfate ion, phosphate ion, methosulfate ion, methanesulfonate ion or p-toluenesulfonate ion.
- the present invention provides two processes for preparing the aforementioned novel SbQ-A salt.
- the first process of the present invention comprises the steps of reacting a compound of picoline type or methylquinoline type with TEA, and purifying the reaction product to obtain pale yellow crystals, and dispersing the crystals thus obtained in water, and adding an alkylating agent of the following formula (3) thereto to obtain the stilbazolium salt.
- the second process of the present invention comprises the steps of reacting a compound of picoline type or methylquinoline type with an alkylating agent of the following formula (3) to form a picolinium salt or methylquinolinium salt, and adding TDA to the solution thus obtained, and heating under reflux to obtain clear yellow SbQ-A salt.
- Compounds of picoline type or methylquinoline type include ⁇ , ⁇ or ⁇ -picoline or 2-, 3-, 4-, 6-, 7- or 8-methylquinoline.
- TDA used in the preparation of SbQ-A salt of the present invention is a compound represented by the following formula (2) :
- R 2 represents hydrogen atom, alkyl group, aryl group or allyl group, and each R 2 may be of the same group and each of the three groups may include hydroxyl group, amide group, carboxylic group, ether bond, double bond, or the like.
- R 2 represents hydrogen atom, alkyl group, aryl group or allyl group
- each R 2 may be of the same group and each of the three groups may include hydroxyl group, amide group, carboxylic group, ether bond, double bond, or the like.
- a representative example is terephthalaldehydemonodiethylacetal.
- the alkylating agent used in the formation of SbQ-A salt of the present invention is a compound represented by the following formula (3) : R 1 - X (3) wherein, R 1 represents hydrogen atom, alkyl group, aryl group, allyl group, aralkyl group or allylalkyl group, wherein hydroxyl group, amide group, carboxylic group, ether bond, double bond, or the like may be included in each group; and X- represents halogen atom, sulfate group, phosphate group, methosulfate group, methanesulfonate group or p-toluenesulfonate group.
- the solvent used in the synthesis of SbQ-A salt according to the first process described above is not restricted, and a mixed solvent of acetic anhydride and acetic acid should preferably be used.
- the temperature of the reaction can be varied depending on the solvent used. The temperature should be between room temperature and 180°C, and the reaction time should be between 1 hour to 24 hours, preferably 7 to 11 hours.
- the solvent used in the synthesis of SbQ-A salt according to the second process described above include polar solvents such as methyl alcohol, ethyl alcohol, or the like.
- Usable catalysts include acids and bases.
- sodium hydroxide, sodium ethoxide, sodium acetate or amine compounds may be used as a base catalyst.
- Use of weak bases rather than strong bases, is more efficient and preferable.
- a representative example is piperidine.
- a compound of picoline type or methylquinoline type and TDA are heated under reflux in a mixed solvent of acetic anhydride and acetic acid for 1 to 24 hours, a large amount of water is added thereto, and the resultant solution is neutralized with dilute alkaline solution to give pale yellow precipitate.
- the precipitate is filtered, and washed with methyl alcohol, isopropyl alcohol, or the like, and filtered and dried to obtain crystals of compound represented by following formula (4) or (4A) :
- R 2 is defined as above.
- a compound of which the acetal site of formula (4) or (4A) has been converted to aldehyde may be detected in a small amount if such acidic solvent was used.
- SbQ salt, not SbQ-A salt is formed.
- the formation of the compound having the converted aldehyde group is caused by water produced by a condensation reaction between picoline or methylquinoline compound and TDA, and acidic solvent.
- a base catalyst is used instead of acidic catalyst since the acetal site of the formula (4) or (4A) may stably co-exist with basic compound though it is fragile to acidic compound.
- R 1 , R 2 and X- are as defined above.
- the salt thus obtained is completely soluble in water.
- a photosensitive resin is prepared by adding acid catalyst such as phosphoric acid to the aqueous solution of the salt and then reacting it with aqueous PVA solution.
- a compound of picoline or methylquinoline type is dissolved in a methyl alcohol solvent and the solution is cooled at low temperature.
- An alkylating agent such as dimethyl sulfate is slowly added thereto to form a picolinium salt or methylquinolinium salt.
- TDA is added, and the mixture is heated under reflux for 30 minutes to about 24 hours.
- Methyl alcohol solvent is removed therefrom by using a rotary evaporator, and the residue is washed with acetone to form a deposit of clear yellow SbQ-A salt crystals. The crystals are filtered and dried to give SbQ-salt having a structural formula or (1) or (1A) as described above.
- the second process of the present invention is different from the first process in that (a) it comprises different reaction orders of the reactants used for preparing SbQ-A salt from those of the first process, and (b) the aldehyde formation of the acetal site caused by the use of acid catalyst in the first process does not occur.
- the second process for preparing SbQ-A salt according to the present invention is more efficient than the first process.
- the SbQ-A salt of the present invention thus obtained, as combined with completely or partially saponified polyvinyl acetate, can be used for the preparation of photosensitive resin having a structure of the following formula (5) or (5A) which can perform a cross-linking reaction upon exposure to light. Such a use also is included within the scope of the present invention.
- R 1 and X- are defined as above.
- the polymerization degree of the polyvinyl alcohol (completely or partially saponified polyvinyl acetate) used for preparing the photosensitive resin by the use of SbQ-A salt according to the process described above, is preferably 300 -3000, and saponification rate thereof is preferably 75% or more.
- the reaction of SbQ-A salt with PVA in the presence of acid catalyst must be performed in a darkroom because the reaction mixture itself exhibits high photosensitivity as the reaction proceeds.
- the reaction temperature is preferably 0 to 100°C, and the reaction time of 1 to 50 hours is sufficient. Since the finished reaction mixture has high photosensitivity, the photosensitivity may be tested with the reaction mixture, or it may be tested after re-precipitating in acetone, methanol, dioxane or the like, extracting with methanol by the use of Soxhlet device and drying.
- the photosensitive resin thus obtained even if the incorporated ratio of photosensitive group is only 1 mol%, exhibits from several to several dozen-folds of activities, as compared to the conventional PVA-ADC type or PVA-diazo type resin. Maximum absorption range appears around 340 nm.
- PVA-SbQ can be prepared by using the same 2 reactors of the conventional processes, though TDA has an acetal group at an end unlike TA. Both processes for preparing SbQ-A need only one reactor, and SbQ-A salt may be used, together with an aqueous PVA solution separately prepared, for the preparation of PVA-SbQ photosensitive liquid in one reactor. It is because an aldehyde formation of the acetal occurs by an acid catalyst during the reaction of SbQ-A salt with PVA, even if one side of TDA is comprised of acetal, and the aldehyde can be reacetalized by reacting with two hydroxyl groups in PVA.
- the acid catalyst has two roles of altering the acetal in SbQ-A salt to aldehyde and of re-acetalizing the altered aldehyde, so that the consumption of the acid catalyst may be reduced. More specifically, one reactor is needed to prepare SbQ-A in the first process, and another reactor is needed to prepare SbQ-A salt by the reaction of SbQ-A with an alkylating agent. An aqueous solution of PVA which have been prepared separately is added to the aqueous solution containing SbQ-A salt, and the mixture is reacted in a darkroom to obtain an aqueous PVA-SbQ solution.
- the same is applied if the acetal site of SbQ-A salt dissolved in water is altered to aldehyde by heating under reflux and then the product is reacted with the aqueous PVA solution.
- one reactor is needed to prepare SbQ-A salt in the second process, and another reactor is needed to dissolve SbQ-A salt in water.
- An aqueous solution of PVA which have been prepared separately is added to the aqueous solution, and an acid catalyst, and the mixture is reacted to obtain a photosensitive resin.
- SbQ-A salt is more efficient than that of SbQ salt. Since the acetal group of SbQ-A salt can be readily converted to an aldehyde group in acidic solution and then can be re-acetalized by reacting with the hydroxy group of PVA, the problems associated with the conventional processes do not exist in the reaction with PVA.
- the process of the present invention is able to prepare PVA-SbQ more efficiently than by the conventional processes, allowing a large scale manufacture of PVA-SbQ resin.
